You've omitted a considerable amount of information, namely: What were the exact steps you've taken to reach the point you are at? I'm assuming you started following the OpenFOAM v4 User Guide at least since the start of Chapter 2: https://cfd.direct/openfoam/user-guide/v4-tutorials/#x4-30002 Furthermore, I'm assuming that you've used "sudo" to copy the 'tutorials' folder... for example, if you ran something like the following commands: mkdir -p $FOAM_RUN cd $FOAM_RUN sudo cp -r $FOAM_TUTORIALS . this would explain why it's not working as intended. None of the official instructions should have told you to do this, therefore it would be very helpful if you please indicate which instructions you were following. If my assumptions/guesses are correct, the solution is rather simple, namely run the following command: sudo chown -R $(id -un):$(id -gn) $WM_PROJECT_USER_DIR echo $WM_PROJECT_USER_DIR The first command will restore the ownership of the path that is given by the second command. Please let us know if this solves your problem. Please also indicate which exact instructions you've followed and which steps you've taken to get here. |

Since I am running Openfoam on university cluster, I am not allowed to use the command 'sudo'. Is there any way to resolve this issue without using 'sudo'? Thanks, Sandipan |

Also, I used the instructions mentioned in https://cfd.direct/openfoam/user-guide/v4-tutorials/#x4-30002 and then I used mkdir -p $FOAM_RUN cd $FOAM_RUN cp -r $FOAM_TUTORIALS . I did not use sudo to copy the files. |

That's what happens when we have to assume a few things... Please provide the following information: 1. Run the following command and show us what it gives you: cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity ls -l 2. Then run the following commands: touch test_create_file ls -l test_create_file What does it show you? 3. Run the following command once again: blockMesh Then please provide the complete output of what it gives you. |

Here is what I got. Thanks. error.png (62,051 bytes) |

r-xr-xr-x means you don't have permission to write files to your system. This is a basic Linux system administration issue, it has nothing to do with OpenFOAM. Read an introduction to Linux, and/or get the administrator of your university cluster to help. Your system appears to be messed up, e.g. some incorrect umask settings, which is the responsibility of your sysadmin. |
